.htaccess made easy brings together a massive amount of information, mixes it with years of experience, and distills it down into a smooth, concentrated blend of .htaccess goodness. In the book, most of the reference-URLs are shortened to help save space and keep things streamlined. The book provides a complete list of around 250 shortened URLs in the appendix (in really small text). The book also includes over 40 URLs that aren’t shortened, and are listed here for the record and because they’re excellent resources.
